Its half MK2, half MK5. I thought as a pistol, the MK5 was better in the back. MK2 parts were cheaper so I subbed those in where I could.

Not entirely sure what needs to be done to the magazine, but I've read that they can modified for 7.62x25 Tokarev, and TOK barrels are available so swapping between 9mm and TOK should just take a barrel swap and magazine mods. Seemed neat.

Still gotta figure out what I'm going to use for a front sight, and clean up the welds. Was actually considering trying to put a small section of rail on it, for a red dot.
